[Cloud Ethernet/ADSL/FTTC] Maintenance window 12th/13th July 2014
Posted by David Croft on 28 June 2014 09:46 AM
Please be advised of the following maintenance window scheduled by BT
on the 20C and 21C networks:

Date: Saturday, 12th July 2014
Start time: 22:00 BST (UTC+0100)
End time: 11:30 BST Sunday (UTC+0100)

Purpose:

BT have advised us that they will be performing maintenance on the
systems supporting their 20C and 21C networks.

Services affected:

Cloud Ethernet (All variants).
ADSL/FTTC (All BT variants).

Impact:

Low.

The 20C and 21C networks will continue to operate as normal, however
the back-end systems supporting them will be out of service for
upgrades.

This includes provisioning but most importantly assurance
functionality. It will not be possible to perform diagnostics during
this window, nor will it be possible to raise faults or schedule
repair.

We are advised that this work will not affect the operation of the
networks themselves, however in the event that an unrelated problem
arises, we will be unable to troubleshoot or raise a fault until the
maintenance is concluded. SLAs during this window are therefore
suspended.

Comtec NOC is tracking this issue under ticket [#GFB-891-27828].

David Croft
